To all whom it may concern:

Be it known that I, WILLIAM B.N on'roN, a citizen of the United States, residing at Detroit, countyof Wayne, State of Mlchi an, have invented a certain new and. useful m- Erovement in Processes of Ornamenting Hot lass or Metal; and I declare the following to be a full, clear, and exact descri tion of the invention, such as will enable -ot 'ers skilled in the art to which it'pertains to 'make and use the same, reference being had to the accompanying drawings, which form a part of this s ecification.

This invention relates to a process of ornamentingglass or hot metal.

' It has for its object an lmproved method of producing ornamental figures or designs upon the surface ,ofeither glass or metal, and

es ecially. upon'glass. v

n carrying out the process the metal'to be ornamented (and k I include in the term metal any material that is suitable for the ornamentation in question and can be heated to a temperature sufficien'tly high to melt the ornamenting material) is heated, the or selected, reduced to a namenting materi'al'is fine filowdenand is applied through a stencil in w 'ch'the openings are through wire-gauze arranged between plates, through which plates there are openings in v ornament to be produced. The plate on the under side of the wire-gauze is thick as compared with the plate on the up er side, and" a the walls of each opening thrdu the thicker under plate form confining-vial s that direct thedust which has sifted through the gauze and cause itto take its position on the article under treatment with sharper and more defined outlines. In applying the dust the box inwhichthe dust 1s contained and on the bottom of which the stencil is placed is held as securely as possible from moving, and the dust is caused to esca e by jarring or tappingthe box and pro ucing' a sharp but almost infinitesimal movement thereofu The article to be treated having been heated to a temperature to melt the particles of dust is placed under the box of. dust and the dust sifted on it in the way mentioned. Im-. mediately the dust melts, forming figures or characters which become rounded on their up er surface because of the cohesion of the me ted particles and which adhere strongly' to the heated article and continue to adhere strongly to the heated article after it cools.

If the article to be ornamented be glass, the.

1 method 0 applying the form of the dust. particles,

fused into the base and the article and t thereonbecome one constituent article and not a basewith an adherent ornamentation. If the article to be ornamented be iron and the ornamental dust be glass, the ornamenta tion adheres as a glazing. The invention, however, is not confined to any articular class. of articles or any articular c ass ofornamentin material, ut consists in the the ornamental material in the ,way described to. a base which is brought to a condition to cause the ornamental material to adhere to it. i

the, subject 'of another application, thought that the process heredescribed will e ornamental figures Although the mechanical features and provements embodied in this invent on form it is which are also of. glass in this ,case, become partiall be more clearly understood by reference to theaccompanying drawings, in whlch Figure 1 shows a section through a stencil-plate. Fi 2 shows asecti'on through a stencil-plate 'fiering in construction. ,Eia; 3 shows a plan of thestencil of which a section is shown in Fig. 1 As stated above, the stencillate is of three layers, of which the inner ayer 2-011 the upper side of the stencil isthin sheet I metal, or if it be made of'thicker material, as

shown in Fi ings bevele to furnish the greatest possible clearance the'box. -The bottom plate or outside plate 1, it has the edges of the openfor the dust that is contained in 4 is thick, and the walls of the,openings continue' through the plate, making an ope of 'uniform'width. The middle plate 5 is 0 thin gauze, and wherever there are letters with detached centers or annular openings the central orfcore parts 7 of said annular openin s are made by riveting the inner and outer p ates together, with the rivet 8 passing throu h the mesh of the screen. Wit the inner plate with beveled sides to through t e screen.

. What I claim is- 1. The process of ornamenting a mineral article, consisting in heating the article to a with wire-gauze, Isaid dust being caused to made thin-or made the stencil-openings V the dust shakes away from the screen and a does not ack and prevent thefree passage fall therethrough and upon said article by repeated sharp jarrings of negligible displacing degree, and being guided in its fall upon the intended portion of the mineral article by the edges of that part of the stencil adjacent to said gauze-covered openings and beneath the plane of the gauze described.

2. The process of ornamenting an article with fusibie material, consisting in heating the article to be ornamented to a temperature to fuse the ornamenting material, and applying said ornamenting material in the form of a dust from a stencil having openings of the shape of the design desired, which openings are covered wit I wire-gauze and t e edges of which beneath the gauze serve to guide the dust in its descent, precipitation of said dust through said gauze being effected by repeated ta ber, substantia lyas described.

3. The process of ornamenting an article,

covering, substantially as consisting in heating the article to be ornamented to a temperature to fuse the ornamenting material, applying the ornamenting r material in the form of a dust by sitting the same through a stencil-like screen, producing the requisite motion for delivering the dust through the screen by repeated jarring and. guiding the dust to its place of deposit after it leaves the screen and between the screen and its final place of deposit, substantially as described.

' 4. The process of ornanienting an article with fusible material, consisting in heating the article to be ornamented to a ten1perature to fuse the ornamenting material, applying the ornamenting material to the article in the form of dust or line powder, which is delivered through a screen and guided between the screen and the ornamented article. substantially as described.

In testimony whereof I sign this specilicw ping upon the stencil memtion in the presence of two witnesses.
